What is the first part everyone change on their new ski?

the impeller

Is there any AM impeller for the 15F?
I need to improve top speed, the acceleration is great but top speed 59.8MPH!!!

Bro, there is nothing wrong with your 15F, with some cooler weather like low 70' deg. air (100% air density) it should do 62 mph with no problem, it's just our local "HAIR DRYER" weather conditions that kills our skis top end speed, for example last Sunday the day that you Gps'd your 15F it was well over 90deg...... also you are not along on this top end speed saga, for example my new RXT was also wayyy...off from his best peak rpm's, according to Riva my ski is suppose to do 7950 peak rpm's in stock form with the stock prop but mine it was doing only 7750 with my lightweight 160 pounds butt on top and with the fuel tank almost empty, a full 200 rpm's shy from his best numbers. About the best all around prop for (ours) 15F "since i still have mine in my garage" i already sent you the info by mail, you just need to get in touch with the person that I told you in my last message, he would make all the arrangements for you, good luck, Ray

p.s. are you ready for "combat zone"

Ok, yes I'll be there with all my family on Saturday. If I find any place to stay, I can stay until Sunday. If not, I drive back home. I will take both skis (Ultra/15F) they're not to fast but we can have fun riding them.

Benjie, how can you say that your two boats are NOT fast??? so a moded ultra with triple pipes it's not a fast boat?? hahaha, you can fool any body but not me even with the 15F in stock form you can do some spanking to some of the moded single pipes yamahas XLT'S from the area, you should holeshot ALL of them with no problem, i did that with mine last year, so you can do the same thing this year with yours, you only need to be carefull to not mess with a guy with a brand new and (almost stock) 215hp SC RXT to give you a hint, he is small and skinny and ride with a complete slippery uniform, as far you don't mess with him you are ok, take care, Ray

Oh really?? hahaha, well then tell him that a guy from the west would be waiting for him with another ("slow" RXT) in the line of fire in playa el combate (combat zone) in this next spring break hollyday weekend to see how true this "fantasy story" is, you just need to show me who is this guy and i would take care of him and ahhh!!! also you can tell him that he is a very lucky guy since the aftermarket R/R external intercooler is currently out of stock, but any way, i am sure that i would not need that to SMOKE him.

Solas offers two Concords for the 15F.

• KG-CD-13/19
  
• KG-CD-14/20

We haven't done any testing as of yet to confirm which is better for a completely stock craft. We hope to soon though.

Can this test be completed before summer?

Hopefully. We're up to our elbows on the 15F Supercharger Kit. It's very involved taking a race kit that we didn't produce initially and configuring it for production/consumer use. Plus, we're having a hard time getting units from Kawi. And when we do get one (or two) they go right back out that same day!
